Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 0.3.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The source enables runtime telemetry by default and sends content-derived hashes and PII metadata on every inspection, without documenting that behavior in the README. The endpoint is consumer-configured and the source does not send the original text, so this warrants a warning rather than a malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-02T05:14:23.132Z - **Finished:** 2026-11-02T05:15:07.107Z - **Download time:** 770 ms - **Static scan time:** 120 ms - **AI review time:** 43084 ms - **Total time:** 43975 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Undisclosed runtime telemetry sends inspection metadata to a configured Supabase database by default. - **Trigger:** Calling GuardBrasil.inspect() with telemetry enabled, which is the default. - **Impact:** Inspection activity and content-derived hashes may be retained by the configured database without the package README disclosing this collection. - **Evidence paths:** dist/guard.js, dist/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T05:15:07.107Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package hashes the inspected text, gathers PII categories and counts, and inserts an event into guard\_brasil\_events through a Supabase client configured from environment variables. - **Rationale:** The source enables runtime telemetry by default and sends content-derived hashes and PII metadata on every inspection, without documenting that behavior in the README. The endpoint is consumer-configured and the source does not send the original text, so this warrants a warning rather than a malicious verdict. - **Network endpoints:** Supabase host configured by SUPABASE\_URL or NEXT\_PUBLIC\_SUPABASE\_URL ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Telemetry is enabled by default in GuardBrasil configuration., Each inspect() call records an event unless telemetry is explicitly disabled., Events include an input hash, tenant ID, PII categories, and finding count., The recorder inserts events into a Supabase table using a URL and key read from environment variables. - **Evidence against:** The event builder records a hash and PII metadata rather than the original text., The telemetry endpoint is configured through the consumer's Supabase environment variables., The only lifecycle script is prepublishOnly, which runs the package build. ## Affected versions and remediation This report applies to @egosbr/guard-brasil@0.3.0. - Review the evidence and your use of @egosbr/guard-brasil@0.3.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
